I can only add to Elena's statement - in fact, it is rather the exception than the rule that a Semantic Web task can be turned into a good game that attracts large, non-nerd audiences. Over the years since our first experiments in 2007, I have come to the conclusion that it is way more rewarding to turn such tasks into Amazon Mechanical Turk tasks (HITs) than to develop games. If we are honest to ourselves, then all of the existing SW games fall short in a terribly in terms of gaming fun and understandability.
The difference between Luis van Ahn's successful games and our attempts of using this for the SW is that Luis used challenges where the processing of visual data and applying linguistic competence are the core intelligence task, two areas that are suited for broad audiences and easily link to entertaining game scenarios.
But validating mapping axioms between bio ontologies and even open street map data is terribly boring in comparison.
Plus, the level of competence needed for cracking the interesting nuts in our data (e.g. subtle forms of polysemy like the city of Munich vs. the district of Munich) restricts the target audience significantly.
To be frank, I consider GWAPs for the Semantic Web a dead end and would not invest additional lifetime into it. It was a promising field back then, and has a lot of appeal at first sight, but it will not solve any of our big challenges.

One of the problems I see, however, is that all data collected through such games is not accessible or reusable by applications (or in other games, as a matter of fact).

Having a standard means to reuse such crowdsourced data sets would make the games definitely more valuable.
